To understand what applications should be moved, when and how, it’s important to create a well attributed catalog of applications managed by IT. Then, the relative importance of each attribute (say, business criticality or amount of system integration) can be weighted and the prioritized list can be built.
You should set priorities within your migration plan based on a combination of business factors, hardware/software factors, and other technical factors. Your business liaison team should work with the operations team and the business units involved to help establish a priority listing that is widely agreed upon. For sequencing the migration of your workloads, you should begin with less complex projects and gradually increase the complexity after the less complex projects have been migrated.
You must account for the following elements when planning and implementing hybrid cloud scenarios.
Networking for hybrid cloud scenarios includes the connectivity to Microsoft cloud platforms and services and enough bandwidth to be performant under peak loads.
Identity for SaaS and Azure PaaS hybrid scenarios can include Azure AD as a common identity provider, which can be synchronized with your on-premises Windows Server AD, or federated with Windows Server AD or other identity providers. You can also extend your on-premises Identity infrastructure to Azure IaaS.
Security for hybrid cloud scenarios includes protection and management for your identities, data protection, administrative privilege management, threat awareness, and the implementation of governance and security policies.
You must develop competencies with cloud technologies and services even as those services evolve and change. Practically, this means that staff must have time to explore new technologies and that you may need to increase your investment in IT staff training.
Rethink your IT service management and disaster recovery practices, as well as how a given cloud service integrates with your existing in-house technology infrastructure. Consider the usage of cloud-based IT service management solutions.
Invest in core capabilities within your organization that lead to secure environments:
